[U-Boot] [PATCH][AT91 rework 0/2] A dummy() implementation _just_ to build drivers/mtd/cfi_flash.c and drivers/block/mg_disk.c drivers.
In AT91 the get_timer(base) returns the elapsed time between the time_start and later after some work. While the "others" are using reset_timer to make epoches and get current time after some work in that epoch.
time_start = get_timer(0) Some work here time_elapsed = get_timer(time_start)

That is unfortunate. I'd like to move that into the SoC specific file. Otherwise that code would be duplicated in each board.

Sorry for that confusion. I just checked the 9261 data sheet and to my surprise the 9261 does not have a MACB or any other LAN interface on the SoC!
It seems that the 9261-ek and derivatives use an external LAN chip, DM9000.
That chip's initialisation, of course, does not belong into the 9261 SoC code.
So it must stay in the board code.

The squashed version is at top of u-boot-atmel/rework-at91sam9261. If you are OK with that, I'll post the patch and apply it to master. (I also changed the subject a bit)

Good, I am OK with that. The pm9261 now boots and the patch will come soon.

Signed-off-by: Asen Chavdarov Dimov dimov@ronetix.at --- Note: This patch was a part of patches, but it is better to be done step by step and so this patch is a split from the patch series with message id: 1307606409-29818-3-git-send-email-dimov@ronetix.at and Patchwork: http://patchwork.ozlabs.org/patch/99666/
Changes for v2: - rename at91_serial_hw_init() to at91_seriald_hw_init()
checkpatch complains at "board/ronetix/pm9261/pm9261.c:148", but checkpatch could be mistaken.
